SuiteCommerce Web Stores

You can optimize your website and decrease page-loading time by caching data and site assets on the Content Delivery Network (CDN) available with SuiteCommerce web stores. After you set up CDN cache, data and site assets that are reused across your web store are always cached. Caching enables reused data and assets to be read quickly, increasing site performance.

Items Cached

The following items are cached by the CDN:

All image files hosted in the file cabinet, identified by filename extensions such as, .gif, .jpg, .bmp, and .png, as well as static file system images that might be referenced from default site templates.

Content in the file cabinet, marked Available Without Login.

Static content (such as text) delivered from the file cabinet that does not contain custom Web Site tags.

The response output from the Item Search API. For example, a request to the Item Search API that returns a list of items.

The response output of executed SuiteScript hosted out of the file cabinet, if it sets response headers indicating the content is cacheable. This refers to SuiteScript associated with SSP applications.

SSP files

Note

Files stored in the file cabinet for sale as download items are excluded from the CDN cache.

CDN Caching Times

You can use the Cache Invalidation Request form to clear the CDN cache, but the browser cache remains untouched. For example, when you invalidate a URL, new customers see new content right away, but returning customers see old content until it expires in their browser cache.

If the CDN cache is not cleared, then CDN and browser cache expire at the same time.

The length of time that a certain type of content is cached also indicates the time it takes for returning customers to see updated content. Note the following:
